how do i find out my ring gear size?

[racer0175]

thinking about getting one of these and i don't know which size ring gear i have. i have a 10 bolt rear (i gotta double check, but im pretty sure) with 4.10 gears

 

my truck is a 1/2 ton 99 silverado z71 4x4 with the hd tow package

 

i checked the rpo's with no luck both here and at alldata....

 

any ideas?

Any dealer parts shop can give you the specifics with the last 8 digits of your VIN - unlikely, but the label may still be on the differential by the filler cap.

You Can also check your glove box for the RPO sticker, get get all your codes and check here

this is easy, go to macromotive.com (where I ordered my power traz Lock Right) and put in the type of vehile you have then search for PowerTrax or Lock Right, untill you find the product, and it will tell you. You probably have a 10 bolt 30 spindle like me.

IF you would like a "real" review first, I should have mine by the 15th and probably installed by the 21(if I can do it myself), and I'll report on how it is.

 

My truck has NO traction in rain, at every stop I spend 15 feet spinning my tires.

and thanks for the info

i put 1999 silverado 1/2 4x4 and it didn't come up with anything at macromotive, if i look down the list though it shows the 10 bolt with either 28 or 30 spline and there was alot more products listed

You have the tow package and not the factory locker?
